Abstract

Described are alkyl-substituted spirodecenone derivatives defined according to the structure: ##STR1## wherein one of R1 or R2 is hydrogen and the other of R1 or R2 is methyl; and wherein R3 represents C3 -C4 alkyl, and uses thereof in augmenting or enhancing the aroma of perfume compositions, colognes and perfumed articles including, but not limited to, solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles and hair preparations; as well as processes for preparing said alkyl-substituted spirodecenone derivatives.

Description

BACKGROUND OF THE INVENTION
The instant invention relates to alkyl-substituted spirodecenone derivatives defined according to the structure: ##STR2## wherein one of R1 or R2 is hydrogen and the other of R1 or R2 is methyl and R3 represents C3 -C4 alkyl, and uses of same in augmenting or enhancing the aroma of perfume compositions, perfumed articles and colognes.
Inexpensive chemical compounds which can provide spicy, floral, rose-like, minty, jasmine and woody aromas with sweet, cardamon, natural balsam, floral, spicy, camphoraceous, vetiver-like, woody, fig-like, and date-like undertones are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute such desired nuances to perfume compositions as well as perfumed articles are high in cost, unobtainable at times, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.
There is, accordingly, a continuous effort to find synthetic materials which will replace, enchance or augment the fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree or they contribute undesirable or unwanted odor to the compositions.
Spiro ketones including spirodecenones as well as spiroundecenones are well known in the prior art and their utilities are known in perfumery.
Thus, Japanese Published Application No. 76/65738 (abstracted at Chemical Abstracts 85:123440f) (corresponding to U.S. Pat. No. 4,052,457 issued on Oct. 4, 1977) discloses the compound having the structure: ##STR3## as being useful in perfumery and further discloses the process according to the reaction: ##STR4##
Nerdel and Dahl, Ann. Chim., 710, 90 (1967) discloses the compound having the structure: ##STR5## and the generic process, to wit: ##STR6## (wherein R represents hydrogen or methyl).
Tanaka, et al, Chem. Comm. 1967, page 188 (title of paper: "The Total Synthesis of Chamigrene" discloses the compound having the structure: ##STR7##
U.S. Pat. No. 4,261,866 issued on Apr. 14, 1981 (Class 252, Subclass 522 R) discloses the genus of compounds having the structure: ##STR8## wherein R1 -R6 each represents hydrogen or lower alkyl. U.S. Pat. No. 4,261,866 discloses the broad genus, to wit: ##STR9## wherein each of the dashed lines represent carbon-carbon single bonds and carbon-carbon double bonds. The compounds disclosed in U.S. Pat. No. 4,261,866 are indicated to be useful in perfumery.
However, the alkyl-substituted spirodecenone derivatives of our invention have unexpected, unobvious and advantageous perfumery properties when compared with the perfumery properties of the prior art.

Referring to FIGS. 6 and 7, the apparatus used in producing polymeric fragrances containing the alkyl-substituted spirodecenone derivatives of our invention comprises a device for forming scented polyolefin (for example) pellets, which comprises a vat or container 212 into which a mixture of polyolefin such as polyethylene and an aromatic substance or scented material is placed (in this case at least one of the alkyl-substituted spirodecenone derivatives of our invention).
The container is closed by an air-tight lid 228 and the air-tight lid 228 is clamped to the container 212 by bolts 265.
A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotated in a suitable manner.
Container 212 having heating coils 212A which are supplied with electric current through cable 224 from a rheostat or control 216 is operated to maintain a temperature inside the container 212 such that polyethylene or other thermoplastic polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ a colorless, odorless polymer (e.g., polyethylene) with viscosity ranging between 180 and 220 saybolt seconds and having a melting point in the range of 200°-280° F. The heater 212A is operated to maintain the upper portion of the container 212 within a temperature range of from 250°-350° F. The bottom portion of the container is heated by means of heating coils 212A heated through control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container within a temperature range of from 250°-350° F.
Thus, polymer (e.g., polyethylene) is added to container 212 and is heated from 10-12 hours whereafter a scented aroma imparting material (at least one of the alkyl-substituted spirodecenone derivatives of our invention) is added quickly to the melt. The material must be compatible with the polyolefin and forms a homogeneous liquid melt therewith. The scented material is of a type for the particular aroma desired and formulated specifically for the scenting purpose for which the polyolefin will be employed.
Generally, about 5-30% by weight of the scented material (containing at least one of the alkyl-substituted spirodecenone derivatives of our invention) are added to the polyolefin.
After the scent imparting material (e.g., a composition containing at least one of the alkyl-substituted spirodecenone derivatives of our invention) is added to the container 212, the mixture is stirred for a few minutes, for example, 5-15 minutes, and maintained within the temperature range as indicated, supra, by means of heating coils 212A.
The controls 216 and 220 are connected, respectively, through cables 214 and 222, respectively, to heating coils 212A. The said controls 216 and 220 are also connected through cables 224 and 226, respectively, to a suitable power supply of electric current for supplying the electric power to the heating coils 212A for heating purposes.
Thereafter the valve "V" is opened permitting the mass to flow outwardly through conduit 218/232 having a multiplicity of orifices 234, adjacent to the lower side thereof. The outer end of the conduit 218/232 is closed so that the liquid polymer (e.g., polyolefin) and aroma imparting material (e.g., at least one of the alkyl-substituted spirodecenone derivatives of our invention) will continuously drop through orifices 234 downwardly from conduit 232. During this time the temperature of the polymer (e.g., polyolefin) and scent imparting material (e.g., a mixture containing at least one of the alkyl-substituted spirodecenone derivatives of our invention) is accurately controlled so that a temperature in the range of from about 210°-275° F. will exist in the conduit 218/232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer (e.g., polyethylene) and scenting material (e.g., one or more of the alkyl-substituted spirodecenone derivatives of our invention) mixture through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.
When the droplets 236 fall onto the conveyor 238 they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 245 and utilized in processes as illustrated, infra.
A feature of this aspect of the process of our invention is the provision for moistening the conveyor belt 238 to insure rapid formation of the solid polymeric (e.g., polyolefin) scented pellets 244 without sticking to the belt. The belt 238 is advantageously fabricated of a material which will not normally stick to a melted plastic but a moistening means 248 insures a sufficiently cold temperature of the belt surface for an adequate formation of the pellets 244. The adequate moistening means comprises a container 250 which is continuously fed with water 254 to maintain a level for moistening a sponge element 256 which bears against the exterior of the belt 238.
THE INVENTION
The present invention provides alkyl-substituted spirodecenone derivatives defined according to the generic structure: ##STR15## wherein one of R1 or R2 is hydrogen and the other of R1 or R2 is methyl; and wherein R3 is C3 -C4 alkyl.
The compositions of matter of our invention produced according to the processes of our invention are capable of augmenting, enhancing or providing spicy, floral, rose-like, minty, jasmine and woody aromas with sweet, cardamon, natural balsam, floral, spicy, camphoraceous, vetiver-like, woody, fig-like and date-like undertones to perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener articles, drier-added fabric softener articles, fabric softener compositions, cosmetic powders, hair preparations, perfumed polymers and the like).
The substances of our invention are prepared by means of reacting an alkylidene cyclopentanone having the structure: ##STR16## with isoprene having the structure: ##STR17## in order to form one or more of the alkyl-substituted spirodecenone derivatives of our invention according to the reaction: ##STR18## wherein R3 represents C3 -C4 alkyl. The reaction takes place in the presence of a Lewis acid catalyst such as aluminum chloride, zinc chloride or stannic chloride, ethyl dialuminum chloride, or diethyl aluminum chloride and in the presence of a solvent inert to the reactants or reaction product such as methylene dichloride, 1,1-dichloroethane or toluene.
The reaction temperature may vary from about 5° C. up to about 50° C. and the reaction time may vary from about one hour up to about fifteen hours.
The mole ratio of alkylidiene cyclopentanone having the structure: ##STR19## to isoprene having the structure: ##STR20## may vary from about 0.5:1.5 up to about 1.5:0.5 with a mole ratio of about 1:1 being desirable.
At the end of the reaction time, the reaction mass is usually washed with such materials as saturated aqueous sodium chloride followed by aqueous sodium carbonate (e.g., a 10% aqueous solution of sodium carbonate).
The thus-washed material is fractionally distilled and the resulting fractions are selected according to GLC, NMR and IR analysis as well as odor acceptability.
Examples of the alkyl-substituted spirodecenone derivatives are set forth in the following Table I:

______________________________________
One or more of the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention and one or more auxiliary perfume ingredients including, for example, alcohols, aldehydes, ketones other than the alkyl-substituted spirodecenone derivatives of our invention, terpenic hydrocarbons, nitriles, esters, lactones, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in the woody, minty, herbaceous, spicy and tagette fragrances. Such compositions usually contain:
(a) the main note or the "bouquet" or foundation stone of the composition;
(b) modifiers which round-off and accompany the main note;
(c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and
(d) topnotes which are usually low boiling, fresh smelling materials.
In perfume compositions, it is the individual components which contribute their particular olfactory characteristics, however, the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.
The amount of the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, cationic, nonionic or zwitterionic detergents, soaps, fabric softener compositions, fabric softener articles and perfumed polymers) and colognes depends upon many factors including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention or even less (e.g., 0.005%) can be used to impart, augment or enhance spicy, floral, rose-like, minty, jasmine and woody aromas with sweet, cardamon, natural-balsam, floral, spicy, camphoraceous, vetiver-like, woody, fig-like and date-like undertones to soaps, cosmetics, anionic, cationic, nonionic or zwitterionic detergents, fabric softener articles, microporous polymers, particularly acrylic resins, polyethylenes and other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.
The alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention are useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders, microporous "perfumed" slow release polymers and the like.
When used as (an) olfactory component(s) in perfumed articles, as little as 0.005% of the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention will suffice to impart, augment or enhance spicy, floral, rose-like, minty, jasmine and woody aromas with sweet, cardamon, natural-balsam, floral, spicy, camphoraceous, vetiver-like, woody, fig-like and date-like undertones. Generally, no more than 6% of the alkyl-substituted spirodecenone derivatives of our invention based on the ultimate end product is required in the perfumed article. Accordingly, the range of use of the alkyl-substituted spirodecenone derivatives of our invention in perfumed articles, per se, is from about 0.005% up to about 6% by weight based on the perfumed article.
In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention. The vehicle can be a liquid such as a non-toxic alcohol, e.g., ethyl alcohol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can be an absorbent solid such as a gum (e.g., gum arabic, guar gum or xanthan gum or combination thereof) or components for encapsulating the composition (such as by coacervation) or using prepolymers such as urea-formaldehyde prepolymers which are able to form a urea-formaldehyde polymer capsule around a liquid perfume center.
It will thus be apparent that the alkyl-substituted spirodecenone derivatives prepared in accordance with the processes of our invention can be utilized to alter, modify or enhance sensory properties particularly organoleptic properties such as fragrances of a wide variety of consumable materials.
The following Examples I and II set forth means for preparing the alkyl-substituted spirodecenone derivatives of our invention. The examples including and following Example III, infra set forth illustrations of organoleptic utilities of the alkyl-substituted spirodecenone derivatives of our invention.
All parts and percentages given herein are by weight unless otherwise specified.
